Terry Byrne

Following Vialli's dismissal, the club's recently appointed chairman, Graham Simpson, promoted Byrne to the post of director of football – a newly created role responsible for player contracts, scouting and the academy. One of Byrne's first tasks was hiring the next club manager, a job that went to Vialli's assistant Ray Lewington. Watford spent most of the 2002–03 First Division season trying to come up with an acceptable financial model that would allow the club to survive now that TV money was no longer there as a revenue source. The cash-strapped club narrowly avoided administration in the 2002–03 season by instituting cost-cutting measures such as forcing players and staff to accept a 12% wage deferral and raising funds via a share issue.

A:3K's main activity is sports entertainment. Specifically, the company puts on entertainment events in indoor arenas during the summer off-season featuring well-known footballers. The shows combine elements of football with performing arts and technology. Byrne put together A:3K Football, a skills challenge event with a futuristic gladiator setting at The O2 arena in London on 17 July 2010 with David Villa, Cesc Fabregas, Cristiano Ronaldo, Didier Drogba, Steven Gerrard and Wayne Rooney. However, the event was postponed after Rooney and Gerrard, two of the most interesting names for the English crowd, withdrew, fearing a backlash for appearing at a highly paid event so soon after England's poor showing in the 2010 World Cup.

In 2010, Byrne helped to revive the New York Cosmos as director of football, working with Pelé and the former Tottenham Hotspur vice-chairman Paul Kemsley.

After ending his role as Beckham's personal manager, Byrne confirmed in January 2009 that he was in talks with the Leyton Orient chairman Barry Hearn regarding a possible takeover by the Byrne-headed consortium. However, this did not materialise.

In 2009, Byrne became a founding partner of Aura Entertainment along with Steve Clarke, David Piper and James Oxley. Aura Entertainment, along with David Gardiner and SEQ, created Arena 3000 (later renamed A:3K), of which Byrne is also a director.

In 2008, 1966 Entertainment launched the Team England footballers' charity which donates players' match fees to their charity partners. The idea arose from Byrne's discussions with the players' committee.

In July 2007, Beckham made the long-anticipated mid-season switch to Los Angeles with Byrne having played a key role in arranging the transfer six months earlier. Some aspects of Byrne's subsequent involvement with the LA Galaxy have been controversial. Through his long-standing relationship with AEG's Tim Leiweke, Byrne became a consultant on the club payroll, which created an obvious conflict of interest, with a player's personal manager also paid for consulting services to that player's club management. Additionally, Byrne's appointment was not revealed to the public or to the club's players. All of this allowed Beckham, Byrne and 19 Entertainment to run the club from behind the scenes. Byrne carried out moves such as requesting the captain's armband to be given to Beckham immediately on joining the team, which eventually created tension with the club's then captain, Landon Donovan. Byrne hired club personnel, ignoring Galaxy's general manager Alexei Lalas, such as bringing Ruud Gullit as head coach in November 2007.

In 2006, Byrne launched 1966 Entertainment Limited, a joint venture with Fuller, and in 2009 Byrne acquired 100% of the company. 1966 Entertainment represents the England football team players' interests in their commercial partnership with the Football Association.

On 31 October 2003, it was announced that Byrne had been appointed as Beckham's personal manager from December 2003.

By Christmas, it was obvious that Watford had no hope of promotion and, coupled with the spring 2002 collapse of ITV Digital, the DTT broadcaster that held The Football League's television rights, the entire Watford project turned into financial ruin overnight. After finishing the 2001–02 First Division season in 14th place, the club ended Vialli's contract two years early and made attempts to avoid administration.

Byrne stayed with Watford for two and a half years before becoming Beckham's personal manager and an executive of Beckham's company, Footwork Productions Limited. In actuality, Byrne had been involved with certain aspects of Beckham's business dealings long before he formally became the player's personal manager. For example, in 2002, on Beckham's behalf, Byrne met with Tim Leiweke, the chief executive of Anschutz Entertainment Group (AEG, the company that owns the Los Angeles Galaxy and at the time also owned four other MLS franchises) in London to discuss Beckham's interest in starting a soccer academy for boys and girls with branches in London and Los Angeles.

Byrne joined Watford F.C. in 2001, brought in by Vialli on a three-year contract. The club drew up an ambitious three-year plan of gaining promotion from the second-tier First Division and returning to the Premiership where it had played during the 1999–00 season. Several high-profile signings, such as 30-year-old Ramon Vega and 24-year-old Stephen Hughes, joined in summer 2001 as the wage bills soared, with even Vialli paid close to £1 million a year. Byrne's exact duties as general manager in Vialli's management team were very loosely defined as he became involved in various aspects of the club's backroom business.

In September 2000, early in the 2000–01 Premier League season, Vialli was sacked by Chelsea. Byrne continued the 2000–01 Chelsea season under the new manager, Claudio Ranieri. At the end of the season, Byrne left Chelsea after nine years with the club, following an offer from Vialli to be a part of his extensive management team at Watford.

In 1999, Byrne's attempt to put the ball back into play during a Chelsea match against Coventry City led to a brawl with the Coventry manager, Gordon Strachan, and along with others he was later fined for misconduct.

Back at Chelsea, Gullit was sacked in February 1998, but Byrne continued under the next manager, Gianluca Vialli.

Byrne's relationship with Beckham intensified during the 1998 FIFA World Cup in France where the masseur became a close confidant to the twenty-three-year-old, helping him cope with the pressures of his first major international tournament. Byrne became the listening post through the player's World Cup ups and downs, such as not playing in the opening group match against Tunisia or his free-kick goal against Colombia. After Beckham was sent off in the second round against Argentina, Byrne alone accompanied Beckham back to the changing room, offering a shoulder to cry on as well as providing continuing support while the English public and the media criticised the player.

In summer 1996, Hoddle was made the England national football team manager and left Chelsea. He took Byrne with him, giving him a position on England's medical staff, although Byrne also continued at Chelsea as the team's assistant physiotherapist in the 1996–97 Chelsea F.C. season under the new manager, Ruud Gullit. Byrne simultaneously performed both jobs over the next three years. He worked for England as one of the team masseurs, rejuvenating tired and injured players between matches. This is where his close friendship with the rising young star David Beckham began to develop.

In summer 1992, Byrne was hired as part-time sports masseur with Chelsea's backroom medical staff, helping out the team physiotherapist on match days. Ian Porterfield was the club's manager at the time. In February 1993, roughly six months into Byrne's time with the club, Porterfield was replaced by David Webb who was in turn dismissed in summer 1993 to make way for Glenn Hoddle.

Terry Byrne (born 4 June 1966) is an English businessman and a director of various companies connected to football that are active in the United Kingdom and the United States. Since 2010, he has been the vice-chairman of the revived New York Cosmos, the soccer club hoping to gain entry into Major League Soccer during the next expansion window.
